So this is based off of part of the book Divergent by Veronica Roth but with it's own Fairy Tail twist. :)
This being a pure "coincidence" on Mira's part, Levy and Gajeel were taking a job together. This job was to hunt down the guild-less dark wizard, Ghoul, and his use of "Fear Magic." According to Levy, such magic was also one of the Lost Magics and was extremely rare, yet powerful. Gajeel was perfect for the job because he seemed to be scared of nothing, and Levy, because well, as long as she knew what to expect from her extensive research, what was there to be afraid of?
"Okay, Gajeel. His magic will put us into a hallucination. This hallucination will induce three of our biggest fears. If we can steady our heartbeat within the fear, then we will be able to move out of the hallucination. That is, if we can't deflect his magic, which I assume both of us will be able to do," Levy said while the two were on the train. She had brought all of her books on the Lost Magic and was reviewing her notes. Gajeel gave her a murmur and looked out the window. He didn't want to watch Levy right now because well… she was pretty. But this fear thing? Phh! Nothing Gajeel couldn't take. If anything, he was fear-less.
Well, they found Ghoul. And well, Iron Dragon Slaying magic couldn't shield them from the vortex they had been pulled into.
"Hey, who turned out the lights!" Gajeel yelled. He could hear and smell a whimpering Levy.
"G-Gajeel? Where are you? I-I can't see!" she shrieked. Gajeel soon found Levy with his sense of smell (and hearing!).
"I'm right here, Levy. Standing in front of you," he said.
"B-but I can't see you. I can't see anything! It's so dark!" Levy put her arms forward and sighed as she felt her guild mate standing in front of her. She wrapped her arms around him.
"So you're afraid of the dark, eh?" he asked amusedly, as Levy tightened her grip.
"Not of the dark," Levy whispered. She was so close now. Gajeel almost (almost!) felt sorry for her, so he tightened his grip, too.
"Then what're you afraid of, Shorty?"
"What's in it."
And as if on cue, the terrifying sounds of monsters and killers and ghosts filled the room with their moaning and howling. They began to attack the mages, one almost tearing Levy away from Gajeel, but his grip was tight. He tried to use his Dragon Slayer magic, but he couldn't.
"You can't use your magic here!" Levy yelled to him over the chaos. She screamed as he heard something graze Levy's back. He held her close now, so that nothing would touch the Solid-Script mage. She just kept murmuring: "It's not real, nothing is real, it will be over, calm down, calm down!" Levy trembled underneath Gajeel. It hurt, being her shield, but like the Shrimp said, it wasn't real.
"You said that if we slow our heartbeats it'll go away, right? So go on, Bookworm. Breathe," Gajeel said, putting his hand over her heart to feel the pulse. The noise in the background was almost unbearable, but he focused solely on her quickly beating heart, trying to slow its pulse.
"In and out," Levy said, almost to herself. It's okay, a voice in her head told her. Gajeel is here. And it isn't real. It'll be over soon, and Gajeel will protect you. Breathe.
And slowly, but surely, with Gajeel holding onto her tightly, the darkness and the noise vanished beside them, and they continued on to Levy's second fear.
